Now uponjthe depressionofi or overflow is avoided; Moreover, the location of the supplemental reservoir below the plane ofthe interior surface of the well-bottom insures the ultimate forcing upward of practically all theink within the stand.

The. construction is extremely simple and inexpensive and can be maintained and used in a cleanly manner. It will also be noted that the sleeve and float can be easily conjointly removed when desired.

The float may be of less length than the sleeve, the only requirement being that it be capable of being depressed below the lower end of the sleeve proper. Furthermore, the float need not closely conform within the sleeve, for if'the holes C are sufliciently restricted in size the practical trapping or iso lation of the ink willstill ensue upon the de-v said. depression, said sleeve containing ,lat-

eral holes establishing communication with the primary compartment, and below which holes the sleeve constitutes a supplementary reservoir, and a pen-float vertically movable within said sleeve and adapted to be depressed to cover said holes for successively isolating a quantity of ink withinthe reservoir and for forcing said ink upward within the float.

2. In an inkstand oi the character deae sc'ribed, a main reservoir, a sleeve closed at its lower extremity and provided with lateral holes a short distance above its lower end which establish communication with the main reservoir, the sleeve below said holesconstituting a supplementary reservoir, a-

pen-float vertically movable within said sleeve and supplementary servoir adapted to force ink to the top of said float.

In ,an inkstand of the character" described, a main reservoir, a sleeve closed at its lower extremity and provided with lateral holes establishing communication with the main reservoir, the sleeve below said holes constituting a -su plementary reservoir, a pen-float vertical y movable Within said. sleeve and adapted'to be depressed below said holes and thereby force a quantity of ink upward to the top of the float.

4. In an inkstand of the character described, amain reservoir, a sleeve closed at its lower extremity and provided with lateral holes establishing communication with the main reservoir, the sleeve below said holes constituting a su plementary reservoir, a pen-float verticaly movable within said sleeve and adapted to be depressed below said holes and thereby force a quantity of ink upward to the top of the float, said lateral 'holes in the sleeve being located below the "plane of the bottom of the main' reservoir for the purpose set forth.

5. In an inks'tand of the character described, a main reservoir containing a primary ink-compartment and a lower depression below the bottom surface of said compartment, a sleeve extending through the main reservoir into the said lower-depression, provided with an opening adapted to admit ink within said sleeve from the reservoir, and a float vertically niovabl'ewithin said sleeve adapted to force ink within said sleeve to the upper end of the float.

6. In an inkstand' of the character described, .a main reservoir containing a primary ink-c'ompartmentand a lower depression below the bottom surface of said compartment, a sleeve extending within said lower. depression provided with an opening adapted to admit ink within said sleeve from the reservoirfand a float vertically movable within said sleeve adapted to trap and upwardly force a quantity of ink to the upper end of said float.
